TO ALL WHOM IT MAYl CONCERN:

Be it known that I, HENRY H. KELLnY,of city and county of Philadelphia,aniLStateof- Pennsylvania,

have invented a new and useful Device for Preventing the Battling ofWindow-subes; and I do hereby declare` the following to be a full,clear, and-exact description of the same, suicient to enable othersskilled in the art to which my invention appertains to fully understandand use the same, reference being had tothe accompanying drawings,making part of this specification, in whichl Figure 1 is a front view ofa window-sash and frame, with myinvention'applied thereto.

Figure 2 is a transverse vertical section thereof, in line :v z, iig. I.I Figure 3 is a similar view in line y y. Similar letters of referenceindicate corresponding parts in the several figures vso that the sashescan be held firmly when at their highest or lowest points.

In the drawings, A represents'an ordinary window-frame, and B the sashthereof. C is an elastic roller, constructed of rubber or other suitablematerial, and having a bearing in arms or brackets, a, which are securedto the bead D, in such a manner that the said roller lshall lievtrausverselyagainst the window-sash B. Its diameter shall be such as tobear firmly againstthe window-sashes, 'yet rotate lfreely, and allow thesashes to be readily raised and lowered. e v f i In order to prevent anyrattling or shaking when the sash is at its highest or lowest point-Isecure to the sash a wedge-shaped block, UE', consisting of a strip'ofmetal, wood, p'orcelaim or other suitable material, con-.

structed'in the form of a wedge, or inclined plane, and secured to thewindow-sash in line with the roller` C, so

as to oo me in contact with it,l whether said roller shall be at the topor bottom of'bead D, or at any'intermediate,

points thereof. V

It will be perceived that when the upper sash is lowered, or the lowersash is raised, the roller will bear against one of the sides of thesash at all times, and thus force said side against the correspondingbead of the window-frame, therebyholding the sash. So soon as the wedgecomes in contactwith the elastic roller, the

Alatter becomes flattened at la certain point lof its periphery, andcontinues to Hatten as the wider part of the wedge is brought againstthe roller. p The friction between the two` increases lgradually untilthe sash'is `entirely raised or lowered, when it will be iirmly held inplace, and will not rattle orv shake,'owi'ng to the pressure of, Atheroller. I i A The sash is easily raised or lowered, since the rollersoon clears the' wedge, and then oil'ers its usual resistance. I amawarethat elastic rollers have been applied to window-sashes and frames,to hold the former at any height, and thus dispense with weights andcords;v and Iam alsol aware that the rollers have been jammed'by meansof diagonal and rounded grooves; butsuchdevices'require to be let intothe wood-work, or necessitate thev cutting of a portion thereof, but myinvention may be a'pplied to any sash'and frame now in use, since it ismerel-y secured thereto, and requires no diiferent construction of theirparts. It is readily applicable to cars, .steamboata and thel like. l

Two wedges and rollers may be placedat corresponding sides of the frameand sash, but one for each willY answer the purpose suciently well.

i The described arrangement' may be reversed; that is to Say, the rollermay be appliedto the sash, and the wedge tothe frame.

Iam aware that the wedge and elastic roller arenot new inthemselves.Having thus described my invention, what- I claim, and desire to secureby Letters Patent, is The' arrangement of the elastic roller C and wedgeE, and operating substantially as herein represented and described. A

To the above I have signed m'y name,'thisveighteenth day of.April, 1868.

y My invention consists in novel means for preventing the rattling orshaking of window-slashes, whether. Acaused by wind, the passing byoi`wagons, or any other cause. l

This is accomplished by applying respectively to the `window-sash andframe, a wedge and an elastic roller, i i
